O'Reilly published 'Excel Hacks,' Second Edition

Millions of users create and share Excel spreadsheets every day, but few go deeply enough to learn the techniques that will make their work much easier. Yet there are many ways to take advantage of Excel's sophisticated capabilities without spending hours on advanced study.

Now expanded to include Excel 2007, authors Dave and Raina Hawley provide a resourceful, roll-up-your-sleeves guide that gives you little known "backdoor" tricks for several Excel versions using different platforms and external applications. Excel Hacks (O'Reilly, $29.99 US) provides more than 130 hacks--clever tools, tips and techniques--that will leapfrog your work beyond the ordinary. [Bill Fox]
